3mmm there will be a change,i have seen in the olympiad corner of mtg infact we are heating the vessel dat contains fluid.
A body is floating in a vessel filled with liquid.now the vessel is heated.the buoyant force on the body incr/decr/remains same??

1see buoyant force depends directly on the mass of the fluid in which its immersed.....and the density variation is anomalus for different fluids.....e.g. water has max density at 4 C....so it can't be said!!!
62The buoyant force is the mass of liquid displaced
if after heating the body, it still floats (whcih it will!) then the wieght of liquid displaced is equal to the weight of the body (which has not changed due to heating.)
Hence there is no chagne in the buoyant force

362hmm... i was answering a different question...
Now i am reading it carefully :P
1i think dere will b no change in d buoyant force as here derez overall no change in d mass of d body n d fluid in which it is emersed..
it will float i think...
24bouyant force is force of displaced fluid....so it will depend on how both the body and liquid expand on heating....
if either body or liquid expands more than the other then there will be change in diplaced volume of fluid...so bouyant force changes....
so without more info ,this ques cant be answered[1]
vaise there was a similar QOD ..on fraction of body immersed after heating..u may read if u r intrested...here is link

1yeah,but dont u think that liquid will expand more as it has a higher value of coefficient of expansion.
24β=2α
γ=3α
these realtions not always true unless mentioned that substances are isotropic in expansion i.e expand uniformly in all 3 directions(X,Y,Z)
